Value, from the Lean perspective, is a capability provided to a customer at the right time at an appropriate price, as defined in each case by the customer.

Lean was coined to describe the Toyota Production System (TPS) during the late 1980s by a research team headed by Jim Womack, at MIT’s International Motor Vehicle Program. It started with “Lean Manufacturing“, then expended to “Lean Services“, “Lean Business“, “Lean IT” and “Lean Management“, and can be simplified using a 5 step principle (Roos et al, 1991; Womack and Jones, 1996):

Identify value: specify what create most value from the standpoint of the end customer.

Create flow: define the tight sequence of value-creating steps so the product will flow smoothly toward the customer.

Establish pull: as flow is introduced, let customers pull value from the next upstream activity.

Seek perfection: optimize the flow by removing waste.

The principles initially introduced by Toyota are somewhat more fundamental than the above 5 steps. There is much more to it as “Lean” must be embedded into long term growth strategies, employee engagement and culture change:

Focusing on long term rather than short term profits.

Putting voice of the customer at the centre.

Exposing issues so that they get resolved.

Optimizing production and avoid over-production.

Creating a culture of immediate problem resolution and first time on-quality.

The Lean enterprise differentiates between waste that is completely unnecessary (such as rework to fix a mistake) and essential non value-added activities (ENVA) (such as regulatory requirements and some management activities). These ENVA activities can be considered as ‘necessary waste‘ which should minimized or potentially outsourced. Toyota has gone to great lengths to put a direct understanding of customer value in the hands of the people who need it most.

Lean Operations to create product development value by enabling companies to do MORE things BETTER, FASTER and/ or cheaper than before.

These goals make sense for customers and for the businesses. Faster time to market puts innovations into customers’ hands more quickly. At the same time, it increases sales and market leadership. Delivering a product with lower costs adds directly to the bottom line, while making products less expensive. Lower costs mean smarter ways of working and continuous optimization. As such, Toyota recently reveals to Autocar its plan to [once again] revolutionise the car factory of the future, which will be able to grow or shrink its production line as required…

Toyota’s new factory will be 25% smaller than existing plants, require 40% less investment and emit up to 55% less CO2.

Toyota’s standard line will be able to shrunk from a 100,000 car-per-year capacity to just 50,000 cars, or vice versa […] to allow capacity to be easily reduced or increased depending on demand.

Toyota’s engineers say the new lines will be 40% cheaper to build and use 40% less energy.

The new factories will also be powered by a number of different energy sources using a new ‘Factory Energy Management System’.
